South Hungerford 2 Watershed Site 9 dam
South Hungerford 2 Watershed Site 9
South Hungerford 2 Watershed Site 9, located in Plymouth County, Iowa, is a crucial water resource managed by the local government and designed by the USDA NRCS. Completed in 1976, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. With a dam height of 25 feet and a storage capacity of 48 acre-feet, the site covers a drainage area of 0.28 square miles and has a surface area of 3.2 acres. The dam is regulated by the Iowa Department of Natural Resources and is classified as having low hazard potential with a moderate risk assessment.
Situated along the TR-Floyd River, South Hungerford 2 Watershed Site 9 plays a vital role in water management and conservation efforts in the region. Despite not having a spillway and being uncontrolled, the dam's design and construction by the Natural Resources Conservation Service ensure its structural integrity and functionality. The site's condition assessment is currently not rated, highlighting the need for regular inspections and maintenance to uphold its effectiveness in mitigating flood risks and providing essential water resources for the community.
In the face of climate change and increasing water-related challenges, South Hungerford 2 Watershed Site 9 stands as a key asset for the local government in Plymouth County, Iowa. With its strategic location, multi-purpose design, and regulatory oversight, the dam serves as a critical infrastructure for ensuring water security, flood protection, and environmental sustainability in the region. As water resource and climate enthusiasts, understanding and supporting the management of sites like South Hungerford 2 Watershed Site 9 is essential for promoting resilient and sustainable water systems in the face of evolving climate conditions.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About South Hungerford 2 Watershed Site 9
Where does the data for South Hungerford 2 Watershed Site 9 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
